My ISFP dad is kind and gentle, yet he shows aggressiveness through indirect attack about everyone. Usually on behaviors. He also describe himself as open minded, yet he has a lot of "hidden" disdain for everyone who is not an SF, and if you tell him directly those issues, he will never admit it, and accuse you of everything you are accusing him. Is this passive-aggressiveness an ISFP tendency ? How can you cope with it ?
